Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed April 17, 1916. Serial No. 91,734.

To all whom it may concern Be it known that I, FRANoIs M. BAKER, a citizen of the United States, resident of Viroqua, in the county of Vernon and State of lVisconsin, have made a certain new and useful Invention in Sash-Adjusting Means; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a side view of the invention as applied with the window shown in section. Fig. 2 is a similar view with the upper sash lowered, the lower sash raised, and the vertical strip removed. Fig. 3 is a section on the line 33 Fig. 1. Fig. 4 is a section on the line, 4:4: Fig. 3. Fig. 5 is a detail perspective view of the channel piece.

The invention has relation to improved means for adjusting the inner .or lower sash of a window toward the upper sash, having for its object to provide improved means for making the sashes tightin the casing, to prevent rattling noises and drafts of air.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2 designates the window casing, 3 the upper sash, and 4 the lower sash.

At each side of the casing is located a vertical strip 5, engaging at its outer vertical edge with the edge portion of the lower sash, said strip being engaged by upper and lower bolts 6, 6, each bolt having at its inner end a nut 7, fitting within a narrow horizontal elongated stationary channel piece 8, located within a narrow elongated shallow recess 8 of the casing, the opposite walls of the nut closely engaging the opposite parallel walls 10 of the channel piece to prevent turning of the nut. The channel piece is of suflicient length to provide a guideway 11 for the nut, and is provided with outer inturned flanges 10, spaced apart from each other by an interval. The recess 8 is of the same dimensions as those of the channel piece fitting therein, and is provided with uninterrupted vertical walls, intersecting the outer lateral walls of the window casing.

The nuts 7 are normally adjusted outwardly by turning the bolts in one direction, to clamp the flanges 10 of the channel piece between the nut and the vertical strip, said strip being thereby held stationary in position adjusted outwardly, to hold the lower sash closely against the upper sash. Upon turning of the heads 14 of the bolts in the opposite direction, the nuts are adjusted inwardly, to loosen the grip upon said flanges, when the vertical strips may be moved inwardly to allow the sashes to be moved vertically, and upon reverse turning of the bolt heads the grip upon the flanges is renewed.

The channel pieces are made each with a back 15 having at one end a perforation 16 for a securing screw, and at its opposite end having a pointed securing extension 17, driven into the wood of the casing.

The vertical strips are preferably provided with beveled outer edges 18, engaging inwardly beveled walls 19 of the lower Sashes.

The side walls of the channel piece extend from the end thereof having the pointed securing extension toward and terminate short of the opposite end of said piece, to leave an uninterrupted opening 19, opposite which the securing screw is located and through which the nuts will pass when the grip upon the flanges is released and the strips, bolts and nuts are slid horizontally and removed. The upper sash may then (in the case of counterbalanced sashes) be lowered and the lower sash raised upon its upper rail as a pivot, a lifting rope 20 being provided for this purpose, said rope being connected at 21 with the lower rail of this sash, passing upwardly over a pulley 22 of a pulley block, and downwardly within reach.

I claim:

In sash adjusting means, a window casing having a narrow elongated shallow recess provided with uninterrupted vertical walls intersecting the outer lateral wall of said casing, a narrow elongated stationary channel piece fitting in and of the same dimensions as those of said recess and having a back provided at one end with a longitudinal pointed securing extension engaging a seat in the end wall of the recess, side walls spaced apart from each other, and outer inturned flanges extending from said securing extension toward and terminating short of the opposite end of the channel piece, to leave an uninterrupted space between said 5 side walls said back having opposite said space a perforation for a securing screw, an adjustable vertical strip, a headed bolt engaging between said flanges and having a nut slidably fitting within said channel 10 piece and capable of passing outwardly through said space, said nut and said strip having normally clamping engagement with said flanges.

In testimony whereof I affiX my signature in presence of two witnesses.

FRANCIS M. BAKER.
